Deletions of 2q14 that include the homeobox engrailed 1 (EN1) transcription factor are compatible with a normal phenotype.

Abstract excerpt

A novel transmitted 2-3 Mb deletion of 2q14.1-q14.2 was found in an affected boy from a consanguineous family with a possible diagnosis of PEHO syndrome (OMIM 260565).
